IMPROVEMENT IN MACI-IINES FOR MELTING SNOW.

y Specication forming part of Letters Patent No. 136,931, dated March18, 1873.

.To all whom t may concern:

Be it known that I, J )HN MULLALY, of NewYork city, in the county ot'New York, and State of New York, have invented certain new and usefulImprovements in Machines for Melting Snow 5 and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and `use it, reference being had to the accompanying drawing whichforms part of this specification.

In the drawing, Figure lis avertical longitudinal section of myinvention, and Fig. 2 is a detail view.

This invention has relation to snow-melters,l and consists in theconstruction and novel ar- 1an gement of perforated cylinder-brush eshaving communication with a steam-boiler, substantially as hereinafterdescribed.

Referring to the drawing, A represents the frame of a snow-machineconstructed with my improvements. It is mounted upon tractionwheels B B,which may be .lianged, if desired, O represents a furnace and boiler forgenerating steam, and D a steam-drum located thereon.

E represent a series of hollow cylinders arranged beneath the furnaceeither laterally, obliquely, or longitudinally. These cylinderscommunicate by pipe connections with the drum D, and the steam conveyedtherefrom is discharged through the perforations or open projections e cupon the snow.

In order to render the operation of these cylinders more effect-ive Iprovide them With brushes, as shown in the drawing; andthe steam beingexpelled thereon will heat and saturate them, thereby facilitating themelting of the snow.

The cylinders may be driven by a gear or equivalent connection with thetraction-wheels or by direct communication with the steamchest, and themachine itself maybe impelled by steam or drawn by animal power.

f In a snow-melting machine, a series of perforated revolving cylinders,constructed and operating substantially as herein described, andmadeeither with or without brushes, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this5th day of February, 1873.

JOHN MULLALY.
